Tok all whom, it may concern,.-

Be it known that I, ANDREW J. ENGLISH, a citizen of the Unitedl States, residingat Cin cinnati, Ohio, have' invented new anduseful Improvements in Gas-Burners, of which the following isa specification.

My invention relates togasburners of the class employed in burning l carbureted air or vaporized gasoline;V77 and it consists in' an improved construction whereby the same are cheapened in cost of construction and their efciency in the vivid combustion of the gas increased. In such burners it'has been found necessary to supply an additional quantity of ytit-y of gas.

the gas around the exterior of the burner proper, and to this end it has been customary to mount the v tip in a metallic casing surrounded with asecondfmetallic casing, leaving an annular chamber,into which the additional gas required is introduced through apertures provided with means of regulating the quan- In burners so constructed. such means of regulation are av vnecessary feature, for the reason that the annular chamberis thus formed of metal surfaces at both sides, and the heat derived from the tipis rapidly conducted away by the inner casing in which the tip is seated. As a consequence, the outer sheet of gas derives no practical benefit from the heat ofthetipk in the way of 'regeneration or heating, and consequently the quantity which can be utilized by the gas-flame must depend upon the atmospheric temperature andbe regu-1 lated accordingly.

In carrying out my linvention no second or extra casing is'necessary. I obtain the annular chamber by enlargementof the containing,- casing, and fit the tip therein, as hereinafter explained, in such manner as to4 utilize the lava tip as a regenerator77 for heating the extra gas passing around the same. The latter feature of my invention and the use made y I thereof renders it unnecessary rto regulate the quantity 'of gas passing into the said chamber,excepting by forming the admissionapertures with proper limitations as to size in the original construction. y

My invention will be bestunderstoodin connection with the accompanying drawing, illusl` trative of the same, in which the gure is a preferred form ofvertical axial section of a the invent-ion complete. n

` by Letters Patent ofthe UnitedStates-- and B the casing or tip-holder, thetwo .to`

gether constituting the burner. Y

, I prefer to give the uppery part of thecasingfi B a'slight' iare and turn the :tip A to `a 'corresponding contour, so as to seat firmlyat the bottom of the flare within the casing.

In the preferred form of my sinvention v (shown in the figure) I reduce the diameter ofj the upper part of the tip, as shown, leaving an annular space, c, between itself and the casing above the shoulder a, ,with the casing extending upward ,to ornearly to the` neck of the tip. The tip otherwiseis of the ordinary construction, hollow within andsemispherical at the top, with anl open slot, s, cut across the top into the hollowinterior. Aperlturesb b are drilled radially through the shell of the tip just above the shoulder a,- preferably ink- 1 clining upward from `Voutside to `inside,in order to admit the extra gas to the annular cham.- ber c thus formed abo-ve ,the shoulder a,and

at thesame time to aid its distributioninto an.

annular sheet within said chamber.- The exber, the inner wall of which' is the material-of` the tip itself, which is highly heatedv bythe flame of gas issuing above, and imparts heatA tothe annular sheetof gas passing through the chamber formed between itself andthe casing., Asa result of this construction, the gasenter.

tra 'gas is thus delivered into an annular chaming theannularchamber is heated more orless f highly before reaching the flame issuing from the upper slot/lof the burnerand nignitesnaacrew readily andatadarenlerel,sothat insteadf taxing the batswing l flame ofthe burner for heat to -raiseit (the extra gas) to the 'point of combustion, (as is the'casein burners of the old construction, to which cause `is due the t necessity of the means of `regulation before're# ferr'ed to,) the annular sheet of gas being al-4 ready heatedintlameslmore readily, and this` condition renders it inXa great degree independent of atmospherictemperature and obvif ates the necessity of special regulating means. y
